Greenwald, Detroit, Mich, assignor, by mesne assignments, to Whitehead & Kales Company, River Rouge, .Mich., a corporation of Michigan Application February 25, 1929. Serial No. 342,647 7 Claims. (01. 126350) This invention relates generally to humiditying systems and consists of certain novel features of construction, combinations and arrangements of parts that will be hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanying 'drawings Y v Figure 1 is a fragmentary side'elevation of a system embodying my invention;

Figure 2 is a fragmentary top plan View of the construction shown in Figure 1 Figure 3 is an enlarged detail view of the coil;

Figure 4 is a perspective view of one of the clamp sections;

Figure 5 is a perspective view of strap; 7

Figure 6 is a fragmentary longitudinal sectional View of the float chamber;

Figure 7 is a longitudinal sectional view through a slightly modified construction.

Referring now to the drawings,1 is a float chamber adapted to receive water from a suitthe steel able source (notshown), 2 is a retort in which Water from the-float chamber is adapted to be converted into steam or water vapor, 3 is an intermediate T-fltting or coupling adapted to receive water from the float chamber 1 and through which steam or water vapor from the T-fltting 3 is adapted to pass to the atmosphere, and '7 is a pipe for conducting such steam or water vapor from the T-fittingto the register. As shown the float chamber 1 is horizontally disposed and is divided by a removable partition 1' into two chambers A and B respectively.

Preferably, the chamber A has a removable closure A provided with an unrestricted inlet port 10 for water, while the chamber B has a passage 1" offset slightly with respect to the port 10 and has a restricted outlet port 11 for water in the bottom thereof. As shown the passage 1"- is adapted to be closed by a float actuated valve 12 that is preferably in the form of a pin havof the partition 1.

ing a pointed end 12' for engagement with the inner end of the passage 1 and having its opposite end pivoted to an arm C of a float D. This arm C is also pivoted to a lateral projection E and falls according to the quantity of water in plane.

Thus as the float D rises the chamber B the valve 12 will move longitudinally toward and away from the passage 1" and will thereby regulate the flow of Water from the chamber. A to the chamber B. With this construction a combined air vent and overflow hole F is provided in the top of the chamber B and a filter G is provided in the chamber A to prevent any foreign matter from entering the chamber B. This filter may consist of any suitable material but preferably comprises wire mesh that extends transversely of the chamber A in spaced relation to the removable parts 1 and closure A and is normally held in place by inwardly extending flanges A'of the latter. The retort 2 is also horizontally disposed and is in the form of a tube or pipe having caps 13 and 14 respectively at its opposite ends. Preferably the cap 13 is imperforate and constitutes a 010- sure for one end of the tube, while the other is provided at the top thereof with an eccentric port 15 that constitutes both a water inlet and a steam or water vapor outlet for the retort. The T-fltting 3 is preferably arranged on one side with the aligned ports 16 and 17 thereof in a vertical plane and with the intermediate port 18 in ahorizontal plane. Preferably this fitting is connected to the float chamber 1 by a clamp 19 and a strap 20 and has the intermediate horizontal port 18 thereof opening toward and in line with the eccentric port 15 of the retort 2. The coil 4 is terminally connected to and suspended from the outlet port 11 of the float chamber and to the lower vertical port 17 of the T-fitting, while the pipe 5 is also horizontally disposed and is terminally connected to the eccentric port 15 of the retort and to the intermediate port 18 of the T-fitting. In fact, the axes of the eccentric port 15, pipe'5, intermediate port 18, and float chamber 1 are all in a common let port 17 in "the T'-fltting 3 is in a plug 1'? that is removable from the bottom of the fitting to enable the same to be drained and cleaned.

Thus with this construction water from a suitable source enters the float chamber 1 and then passes through the coil 4, T-fitting 3 and pipe 5 to the retort 2 where it is converted into steam or water vapor which passes from the retort through the pipe 5 to the T-fitting and thence through the pipe '7 to the register 6. In this connection it will be noted that the strap 20 and clamp 19 connections between the float chamber 1 and T-fitting 3 are such that the float chamber 1 may be raised or lowered with respect to the T-fitting 3 to regulate the action Moreover, it will be noted that the outtion in which the fioat chamber is bolted directly to one end of the T-fitting 31. Nith this construction a flexible tube 32 of substantially U-formation is terminally connected to and suspended from the water. inlet port 17 of the T-fitting and the'water outlet port 11 of the float chamber and a plurality of removable plugs 33 and 34 respectively are provided in a plug 35 in one side of the T-fitting to enable the level of the water in the said fitting to be readily ascertained. Moreover, slots 36 and 3'7 respectively are provided in the attaching flange 38 of the float. chamber 30 to enable the float chamber 30 to be raised. and lowered relative to the T-fitting 31 and securing bolt '39 to regulate the Water level in said fitting and retort.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to What is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What I claim as my invention is:

1. In a humidlfying system, a fitting having an outlet for steam, a float chamber carried by and adjustable vertically relative to said fitting, means for conducting water from the chamber to the fitting, a retort, and means for conducting Water from the fitting to the retort and for conducting steam from the retort to the fitting.

2. In a humidiiying system, a fitting having an inlet for watenan outlet for steam and an opening constituting combined outlet for. water and an inlet for steam, a float chamber ing an openingconstituting an inlet for water I and an outlet for steam, and associated with the openings the fitting and retort respectively for conducting water from the fitting to the retort and for conducting steam from the retort to the fitting.

3. In a humidifying system, a fitting having an outlet for steam, a float chamber for water atone side of said fitting and supported thereby for vertical adjustment relative to said fitting,

means for vertical movement relative thereto for controlling the depth of water in said retort and said means, and means for conducting water from said chamber to said connecting means whereby simultaneously water is conducted to and steam discharged from said retort through'said connecting means.
